Garbage bin, bin lid and rotary packing mechanism

Abstract

The present disclosure relates to a garbage bin, a bin lid, and a rotary packing mechanism for garbage bin. The rotary packing mechanism for garbage bin comprises an annular storage box for storing garbage bags and allowing the stored garbage bags to expand downwards, and a rotary driving device for driving the storage box to rotate, wherein a throw opening is formed at the middle of the storage box for throwing the garbage into the garbage bag. The rotation of the storage box makes the garbage bag that is expanded downwards and stored with garbage rotate, whose upper end is twisted and sealed. The rotary packing mechanism twists the seal in a manner of rotating the storage box, the seal is tighter, the garbage inside is not easy to leak, and the seal is small, which is conductive for subsequent automatic cuttings.
